On Lost Girl, Bo and Kenzi get a taste of suburban hell and we finally find out what Kenzi smells like.

This week’s episode (“Adventures in Fae-By Sitting”) starts out like those fun Lost Girl episodes of old, with Bo and Kenzi bantering in their apartment. Bo’s love life is empty, but she points out that Kenzi doesn’t do much dating either. “I have a rich inner life.” “That reminds me, I need new batteries.”

Then a case comes walking in the door, a cute babysitter who found one of their old flyers in a coffee shop. Seems she had a bad dream and thinks foul play is afoot in ye olde gated community. They agree to take the case.

A little undercover work turns up a disturbingly perky real estate agent, a mildly creepy neighbor, and a book club of wealthy women that talk so fast I felt exhausted just listening to them. The neighborhood seems to have suffered an unusual amount of disappearances and murders. There’s also a creepy carousel that doesn’t have anything to do with anything.

They find out the babysitter client is a duppy, a fae creature who is dead but can be invoked every 100 years and forced to commit murders. The folklore origin comes from West Africa, where duppies are evil spirits bearing no resemblance to their Lost Girl form. To help save the duppy (whose name is Lisa), Kenzi takes over her babysitting gig for creepy next door neighbor, who is apparently totally unconcerned that a total stranger arrives to care for his son in place of the usual girl.

The “Kenzi babysitting” sequence starts out pretty boring and predictable, and then out of nowhere the bratty kid tells her she smells like gasoline, then runs away. Later, Kenzi tells him the story of SuperKenz, a superhero with all the powers of Kenzi’s fae friends. It’s become obvious that Kenzi will acquire fae abilities at some point this season.

Bo’s investigation uncovers a coven of suburban witches who are super, super eager to tell her all about all the men they’ve killed. Seriously, they just met Bo that day and they invite her to join their little circle and immediately spill the beans on a whole series of murders. The whole encounter does give us some wonderful bits of dialog, like Bo: “You bitches are witches!” And the following exchange when Bo does her succubus thing:

“That is better than sex.”

“Then you’re doing it wrong.”

Anyway, Bo does some kind of magic fae thing, breaks the control they have over the duppy, and dissolves the two women in a sort of summary fae execution. Then the random creepy carousel plays “The Wanderer.” The whole story is wrapped up neatly when Bo mercy-kills the duppy and destroys the magic necklace so she can’t be summoned any more.

Despite the total lack of nudity or any sex scenes, something about the whole upper class housewives scenario made this episode feel more soft-core porny than any this season. Or maybe it was just Bo in that red dress. Or the babysitter. Or maybe it's just me.

Lauren, in a completely disconnected sub-plot, asks for a leave of absence, but Hale the Ash acts like a huge jerk and just reminds her that he owns her. Her scientist friend Isaac keeps coming by to offer her a job. He eventually reveals that he’s uncovered Lauren’s terrible secret: a truly unforgivable haircut. And that her real name is Karen Beattie, a woman who apparently has something to hide. She leaves with Isaac for a long-term engagement, leaving her cell phone behind.

But really the most interesting part of this episode was the strange tale of Dyson and Tamsin. Most interesting and most hilarious. First, an attractive blonde comes to the police station to ask Dyson for help finding her missing twin sister, who he knows is the fae that turned up dead after sleeping with Bo. Tamsin shows up to work drunk.

Here’s what these ace detectives do. First, they jump on this case, a case they’ve completely ignored for about a month. Then, Dyson notices a clue. The strangle marks on the victim’s neck clearly show a six-fingered hand. I can’t even fathom what terrible, terrible detective work is required to miss a clue like that for weeks and weeks. Don't worry, Detective Drunk Valkyrie and Detective Werewolf With His Head Up His Ass are on the case!

They head out to a field and Dyson smells death. Once excavated, they find a gruesome collection of fae corpses. All fae killed by other fae. Dyson spots a Karina (Carina? Koreena?), which he says he’s never seen outside Egypt. Based on Dyson’s pronunciation, I couldn’t figure out what the folklore analog is. I'm open to guesses/readers who are more knowledgeable than I. This fae has a “feeding signature” similar to a succubus, so they figure the Karina killed Bo’s lover at the mass grave, then dragged the body to where it was found. And then someone else killed the Karina and put it in the mass grave? Does that make any sense to anyone?

[Update: It's a qarînah, which is essentially, "a succubus, but from Arab folklore instead of western folklore." Thanks to luckymc44 for the tip.]

Tamsin almost confesses that “some serious shit is about to go down,” but the corpsefest interrupts her. We end with the observation that something is hunting fae. And the observation that a camera has been observing them the whole time.
